Title: Arithmetic method for circular arc interpolation of numerical control
Inventor: MANABE TAKAO
IPC: G05B19/18
Filed: 1986-03-04
Abstract: PURPOSE:To improve the follow-up accuracy even in a high-speed feed mode by calculating a reduction amount of the radius to a commanded circular arc, adding this radius reduction amount to the circular arc interpolation data for correction of the shift data and therefore eliminating the radius reduction amount. CONSTITUTION:The radius reduction amount is calculated for each sampling, for example, based on the radius of a commanded circular arc, the feed speed, the override of the feed speed, the position loop gain constant and the acceleration/deceleration time constant. The calculated radius reduction amount is added to the circular arc interpolation shift data for correction of the shift data. Thus the radius reduction amount is eliminated in a circular arc interpolation mode and the actual tool locus can be set close to the NC program command value as much as possible. Furthermore the feed speed limited in the circular arc interpolation mode is increased for reduction of the working time.

Abstract: PURPOSE:To prevent over current flow through a switching circuit by detouring supply of electricity from a control means to the switching circuit through a safety means upon contact of first and second connecting means arranged in a communication means. CONSTITUTION:In a case where a worker shortcircuited a first connecting terminal 31 or a first connecting cable 32 erroneously to a second connecting terminal 33 or a second connecting cable 34, electricity is not fed to the inverting circuit 51 of a switching circuit 5 because the resistance of a resistor 81 in a safety means 8 is set lower than the resistance of a resistor 54 in the inverting circuit 51 of the switching circuit 5. In other words, electricity is fed from a CPU 6 only to the bypass wiring 83 of the safety means 8 while detouring the switching circuit 5.
